Fireproof board

ABSTRACT

A fireproof board includes a fireproof layer comprised a mixture of expandable graphite and fibers, and a decoration layer laminated on one side of the fireproof layer, and a substrate layer disposed to the other side of the fireproof layer. In case of a fire, the expandable graphite will expand rapidly and grow into vermicular intumescence, tangling with fibers to form a fire resistant layer can stop the flame spread and reduce the smoke development for achieving fireproof purpose to protect the objects covered over by the fireproof board.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention is related to a fireproof board, and more particularly to a board that is capable of stopping the flame spread and smoke development for achieving fireproof purpose thus to protect the inflammable object, e.g., partition board, furniture, or cabinet covered over by the fireproof board.

(b) Description of the Prior Art

Use of constructional materials in board form has become so intimate with people today. The board is widely used as the face panel in the partitioning system, office furniture, office cabinets, interior furniture at home, etc.

The traditional board materials may be adhered to a building, used as a decorative partition pasted with wallpaper, or finished with a decorative face layer to be attached to apiece of furniture or cabinet. However, in case of a fire, the inflammable board caught fire inevitably, and the burning board not only fails to protect the object but also helps accelerate the fire extension, and to cause the loss of life and damage to properties in serious case.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a fireproof board that stops the fire from extending and mitigates the diffusion of smokes for achieving fireproof purpose thus to protect the objects covered up by the fireproof board.

To achieve the purpose, the fireproof board of the present invention includes a fireproof layer comprised a combination of expandable graphite and fibers, and a decoration layer laminated on one side of the fireproof layer; and a substrate layer disposed to the other side of the fireproof layer so that in case of a fire, the expandable graphite will expand rapidly and grow into vermicular intumescence, tangling with fibers to form a fire resistant layer can stop the flame spread and reduce the smoke development for achieving fireproof purpose to protect the objects covered over by the fireproof board.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, a first preferred embodiment of the present invention includes a fireproof layer 11 and a decoration layer 12. The fireproof layer 11 comprised a combination of expandable graphite 111 and fibers 112. The fibers 112, may be related to chemical fibers, paper fibers, natural fibers or mineral fibers, combined with expandable graphite punched in shape by using the process of non-woven fabric and then hot-compressed into a sheet or a roll of the fireproof layer 11. The decoration layer 12 is disposed to one side of the fireproof layer 11. An adhesive layer 13 is sandwiched by and binds the fireproof layer 11 and the decoration layer 12 to each other.

In practice, the fireproof board may be erected as a face panel on a partitioning board, office furniture, office cabinet, or interior furniture at home. As illustrated in FIG. 3, a fireproof board 1 of the present invention is used as a face panel on a partitioning board in a building with the decoration layer 12 facing outwardly. Of course, the decoration layer 12 may be provided with expression of different patterns or graphics to deliver attractive appearance. In case of a fire, the expandable graphite 111 will expand rapidly and grow into vermicular intumescence, tangling with fibers 112 to form a fire resistant layer can stop the flame spread and reduce the smoke development for achieving fireproof purpose to protect the partitioning board covered over by the fireproof board 1.

Now referring to FIGS. 4 and 5 showing a second preferred embodiment of the present invention, the fireproof board 1 further includes the fireproof 11, the decoration layer 12, and a substrate layer 14. Similarly, the fireproof layer 11 comprised a combination of expandable graphite 111 and fibers 112. The fibers 112, may be related to chemical fibers, paper fibers, natural fibers or mineral fibers, combined with expandable graphite punched in shape by using the process of non-woven fabric and then hot-compressed into a sheet or a roll of the fireproof layer 11. The fireproof layer 11 is disposed between the decoration layer 12 and the substrate layer 14; the decoration layer 12 is disposed to one side of the fireproof layer 11, and the substrate layer 14 is disposed to the other side of the fireproof layer 1 in relation to the decoration layer 12. The adhesive layer 13 is sandwiched by and binds the fireproof layer 11 and the decoration layer 12 to each other; and another adhesive layer 13 is sandwiched by and binds the fireproof layer 11 and the substrate layer 14 to each other. The substrate layer 14 may be related to a paper board, wooden board, plastic board, plastic film or a fabric.

As illustrated in FIG. 6 showing a third preferred embodiment of the present invention, a fireboard 1 further includes the fireproof layer 11, a flat layer 15, the decoration layer 12, and the substrate layer 14. Again, the fireproof layer 11 comprised a combination of expandable graphite 111 and fibers 112. The fibers 112, may be related to chemical fibers, paper fibers, natural fibers or mineral fibers, combined with expandable graphite punched in shape by using the process of non-woven fabric and then hot-compressed into a sheet or a roll of the fireproof layer 11. The fireproof layer 11 is disposed between the decoration layer 12 and the substrate layer 14; and the flat layer 15 is disposed between the decoration layer 12 and the fireproof layer 11. The flat layer 15 may be related to a piece of paper, paper board, plastic board, plastic film that is capable of making the surface flat. The fireproof layer 11, the flat layer 15, the decoration layer 12, and the substrate layer 14 are bound in position to one another with the adhesive layer 13 sandwiched between any two layers. The substrate layer 14 may be related to a paper board, wooden board, plastic board, plastic film, or fabric.

In practice, the fireproof board 1 may be made a face panel on a partitioning board in a building as illustrated in FIG. 3, or on a cabinet or counter at home as illustrated in FIG. 7. In either case, the decoration layer 12 faces outwardly. Of course, to achieve the purpose of having an attractive appearance, different patterns or graphics may be made on the decoration layer 12 as desired by the owner. Meanwhile the substrate layer 14 also provides support effects to the piece of furniture it is attached to. In case of a fire, the expandable graphite will expand rapidly and grow into vermicular intumescence, tangling with fibers to form a fire resistant layer can stop the flame spread and reduce the smoke development for achieving fireproof purpose to protect the partitioning board or cabinet or counter covered over by the fireproof board.
